Great Tree Roots

Back in Arbor after the events in Urbeth, you'll find yourself again in control of the princess, who is still in feline form. Since your traveling companion is also stuck in his story state as a plant, you'll have to work on your own for now. Head toward the north side of the town and pass through an opening to enter the inside of the large tree. There, you can head right to find a shops where you can purchase the Sacred Tree Staff to improve your magic attacks. The Salve-maker Robe is also a wise investment.

When you're properly equipped, head to the lower right portion of the inner tree, to the right of the inn's front desk and down some stairs. From there you can pass into an underground area.

In the underground area where you appear, head to the right until you come to a mouse who is standing in the passage. Talk to him for a scene. When it concludes, Torte will join the party. He's equipped with powerful magic. Head down the path from where you meet with him. You'll come to a fork in the path where you can head either left or right. Start by following the left pathway to find a treasure chest that contains the Great Tree Harp, which the princess should equip immediately. Then return to the fork in the path and this time continue along it toward the right.

You'll follow the path in that direction as it winds its way around a few sharp bends. Finally, you'll reach the top of a staircase. Descend it to the lower floor, then head down to reach a fork in the path. You can head left here to find a treasure chest that contains a Phoenix Down item if you wish. Otherwise, just save yourself some time and follow the branch toward the right.

Continue in that direction and shortly you'll reach another branch in the path. Head left at this one, then keep following the trail until you reach another branch. Here, head to the right. Follow that until you come to another intersection where your choices are to either head right or to continue going up along the screen. Choose the latter option and you'll find a treasure chest. Open it to obtain the Animal Staff, which is what prompted your visit to this location. Now just return to the surface.

With the staff now in your possession, you can do something about your friend's sorry state. Visit him and use the staff. He'll turn into a dog and join your party. Now you should look into finding him some powerful equipment, including the Red Shot weapon for whoever will be serving as your fighter. You have a proper party again, so you can assign skills that will help you in challenging battles to come.
